DRIVER EXPECTANCY CHECKLIST

EXISTING COMMUNICATION SYSTEMS BETWEEN THE HIGHWAY AND THE DRIVER ARE SOMETIMES INADEQUATE FOR ONE OR MORE OF THE FOLLOWING REASONS: (1) FAILURE TO COMMAND THE DRIVER'S ATTENTION WHEN IT IS NECESSARY FOR HIM TO MAKE A VEHICULAR CONTROL DECISION; (2) FAILURE TO CONVEY A CLEAR MESSAGE, THUS LEADING THE DRIVER TO MAKE AN INCORRECT DECISION RESULTING IN IMPROPER MANEUVERS AND SOMETIMES LOSS OF CONTROL OF HIS VEHICLE; (3) PROVISION OF TOO MANY MESSAGES FOR DRIVER COMPREHENSION AND PROPER RESPONSE; AND (4) FAILURE TO PROVIDE THE DRIVER ENOUGH TIME TO RESPOND WITH THE CORRECT VEHICULAR CONTROL DECISION. IN 1968 A PROJECT WAS UNDERTAKEN TO DEVELOP A METHOD FOR STUDIES OF HIGHWAY VISUAL COMMUNICATION SYSTEMS, TO DEMONSTRATE THE APPLICATION OF THIS METHOD ON SECTIONS OF SEVERAL TYPES OF HIGHWAYS, AND TO REPORT SPECIFIC FINDINGS FOR IMPROVEMENTS IN THE EXISTING VISUAL COMMUNICATION SYSTEMS. UNDER A RESEARCH CONTRACT THE TTI STAFF MADE A STATE-OF-THE-ART REVIEW, DEVELOPED THE STUDY METHOD, SELECTED STUDY SECTIONS, CONDUCTED THE SAMPLE STUDIES, AND PREPARED SUMMARY REPORTS. A MULTIDISCIPLINE DIAGNOSTIC TEAM APPROACH WAS USED AS THE PRINCIPAL METHOD OF RESEARCH. ANALYSES OF THE TOTAL DATA INTO A PROJECT SUMMARY REPORT LED TO CONCLUSIONS FOR FURTHER STUDY OF "DRIVER EXPECTANCY" (THE TOTAL OF VISUAL CLUES THE DRIVER RECEIVES WHICH PREPARES HIM TO EXECUTE A PARTICULAR MANEUVER) WHICH WAS A MAJOR FACTOR EVIDENT ON ALL SECTIONS DRIVEN. ONE OUTGROWTH OF THIS RESEARCH WAS THE DEVELOPMENT OF A DRIVER EXPECTANCY CHECKLIST WHICH CAN BE EFFECTIVELY USED AS AN AID TO DECISION MAKING BY BOTH THE DESIGNER AND THE ADMINISTRATOR. /AUTHOR/
